GATORADE ENDURANCE

TRAIN WITH WHAT’S ON COURSE.

We see you out there putting in the training to get ready for the Bank of America Chicago Marathon! Gatorade Endurance products are created specifically to help tough athletes like you replace the fluids and electrolytes lost when training and racing over prolonged periods. These products are backed by over 50 years of nutrition and hydration research at the Gatorade Sports Science Institute (GSSI). They deliver a 2:1 glucose:fructose blend that helps the body maximize carbohydrate absorption while minimizing GI distress. That means that with each serving, you’ll get the fluids and nutrients you need to dig deeper and work harder. Gatorade Endurance Formula will be available on-course at every aid station, delivering the fuel to unlock your best, start to finish.
